Abstract
The present invention provides a road lighting fluorescent lamp. A high-voltage sodium lamp is generally used as a traditional lamp for illumination of roads, which has the problems that the maximum light can be output and concentrated at 580 nm, the stimulating value for people's eyes is very low in mesomeric vision, and the effective light flux is low; in addition, because the distance of 580 nm belongs to a yellow light zone, the high-voltage sodium lamp nearly does not have blue green light. Thus, the road lighting fluorescent lamp which is provided by the present invention comprises a lamp tube, wherein the main peak value of the luminous wavelength of the fluorescent powder which is coated in the fluorescent lamp tube is 516+/-10 nm; on the other hand, the secondary peak value of the luminous wavelength of the fluorescent powder which is coated in the fluorescent lamp tube is 480+/-10 nm, 450+/-10 nm and 611+/-10 nm. The distribution of the light which is emitted by the road lighting fluorescent lamp provided by the present invention accords with the spectrum sensitivity of the mesomeric vision between the photopic vision and the scotopic vision of people's eyes; thus, people's eyes can obtain optimal effective light flux under the road lighting mesomeric vision environment, and good correlated color temperature and a high color rendering index can be ensured.
Description
Technical field
The present invention relates to a kind of fluorescent lamp, relate in particular to a kind of fluorescent lamp that is used for road lighting.
Background technology
Road lighting is the pith of countries in the world urban development and variation.The illumination expert thinks that with the Human Physiology expert is consistent light efficiency height, the road lighting light source that color rendering is good, energy consumption is low, the life-span is long and light pollution is little are the developing direction of road lighting from now on.Road lighting is at present mainly adopted has higher luminous efficiency and long-life high-pressure sodium lamp, substitutes traditional incandescent lamp and high-pressure mercury lamp, becomes topmost road lighting lamp.But, particularly find the visual effect needs of night vision environment and the light output-index of high-pressure sodium lamp are had evident difference after deliberation according to human eye along with people improve constantly the requirement of road lighting.Mainly there is following some serious defective in the high pressure sodium lamp that uses at present:
1, the high-pressure sodium lamp emission spectrum does not meet the road lighting requirement
Know from the analysis of human eye physiological structure, have two types photosensory cell in the human eye retina, i.e. cone cell and columnar cell, they respectively under different lighting environments the reaction to spectral sensitivity be different (seeing also three curves among Fig. 1).Fig. 2 shows the constitutional diagram of high pressure sodium lamp spectral distribution curve and human eye spectral response curve, and as can be seen from the figure, the emission spectrum of high-pressure sodium lamp relatively is adapted at ambient brightness 〉=10cd/m
2The photopic vision environment, and to noctovision or near scotopic ambient brightness at 0.5-2cd/m
2During mesomeric vision, main peak value 580nm is not high to very low its effective luminous flux that sends in other words of values of human eye.
2, high-pressure sodium lamp photochromic poor, color rendering index is low
The luminous energy output of high-pressure sodium lamp maximum concentrates on the yellow area about 580nm, almost do not have blue green light and a small amount of ruddiness is only arranged, thereby high-pressure sodium lamp is photochromic very yellow.Watch object this under photochromic, visual sense feeling is unclear, can produce a kind of dim sense, and diopter is bad.In addition, general high voltage sodium vapor lamp color rendering index only is 23, and color reductibility is just very poor.
3, the actual energy-saving effect of high-pressure sodium lamp is unsatisfactory
The 580nm fluorescence that high-pressure sodium lamp sends, the visual sensitivity to human eye in the road lighting environment is not high, thereby its effective luminous flux is lower, finds through accurately calculating, and only is the 1/3-1/4 under the photopic vision environment usually.Therefore, the power that the high-pressure sodium lamp that road lighting is used uses is higher, has wasted the road lighting power consumption greatly.
Summary of the invention
Therefore, the objective of the invention is to, a kind of road lighting fluorescent lamp efficiently that meets the mesomeric vision spectral sensitivity between human eye photopic vision and noctovision is provided according to above-mentioned analysis.
Another object of the present invention is to provide a kind of road lighting fluorescent lamp that can improve light source color temperature and color rendering index.
According to conventional high-tension being received the analysis of lamp, because the spectrum of high pressure sodium lamp emission does not meet the physiological property of human eye in the mesomeric vision environment, thereby cause the not high shortcoming of effective luminous flux, fluorescent light provided by the invention comprises a fluorescent tube, its characteristics are that the emission wavelength main peak value of coated electroluminescence fluorescent material is 516 ± 10nm in this fluorescent tube.
According to above-mentioned fluorescent light, the emission wavelength minor peaks of coated electroluminescence fluorescent material is 480 ± 10nm, 450 ± 10nm and 611 ± 10nm in this fluorescent tube.
According to above-mentioned fluorescent light, the emission wavelength minor peaks of coated electroluminescence fluorescent material is 545 ± 10nm, 480 ± 10nm and 611 ± 10nm in this fluorescent tube.
According to above-mentioned fluorescent light, the emission wavelength minor peaks of coated electroluminescence fluorescent material is 450 ± 10nm, 480 ± 10nm, 545 ± 10nm and 611 ± 10nm in this fluorescent tube.
As mentioned above, the distribution of the disclosed light that fluorescent light sent meets the mesomeric vision spectral sensitivity between human eye photopic vision and the noctovision, realize under road lighting mesomeric vision environment, making human eye can obtain best effective luminous flux, and guaranteed to have good correlated colour temperature and higher color rendering index.
